A hot air ballons is rising upward with a constant speeed of 3.00 m/s. When the ballon is 25.0m above the gound, the ballonist releases a sandbag. Air resistance is negligible in this problem. in this problem, choose the +y-axis to point up the page.
A) What is the initial velocity of the sandbag immediately before it was released?
b) To what maximum height does the sandbag rise?
c) What is the speed of the sandbag immediately before it hits the round?
